I-IOISTTNG DEVICE FOR ENSILAGE-BLOWERS.

Specification of Letters Patent.

Application filed-November 14, 1916. Serial No. 131,322.

- improved device for hoisting the blower pipe of an ensilage chopperinto proper position to be supported with respect to a silo in such amanner as to deliver the ensilage therein.

The invention has for its object to produce an improved crane includinga frame, means for supporting the same in position on a silo, a step tosupport the operator, hoisting means forelevating the tube, and meansfor securing the tube in position.

A further object of the invention is to produce a device of thecharacter described which will besimple in construction, inexpensive andeflicient in operation.

With these and other ends in view which will readily appear as thenature of the .invention is better understood, the same consists in theimproved construction and novel arrangement and combination ofpartswhich will be hereinafter fully, described and par ticularly pointed.outqin the claims.

In the accompanying drawings'has beenv illustrateda simple ,andpreferredform ofthe invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and'modifications within the scope of theclaims may be resorted to when desired.

In the drawings,-

Figure 1 isa perspective view showing the improved crane applied to asilo and with the blower "pipe in process of being hoisted intoposition.

Fig. 2 is a perspective view showing the blower pipe hoisted andadjusted for operation. 4

Fig. 3 is a side view of the crane detached.

Fig. 4 is a front view of the same.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The frame of the improved crane is composed of side memberseachconsisting of a metallic bar 15 having a quarter .-twisted portion16 intermediate the ends thereof, the lower end being bent at rightangles to the body of the bar to produce a forwardly extendlng arm 17having at its forward end an upturned hook 18. Each side member 15isbent at the u pper end thereof to produce a laterally extending loopor keeper 19. The arms ,17 of the two side members support. a step orplatform 20 which may be bolted or otherwise secured on said arms, asshown at .21. The forwardedge of the'step or platform is also insertedbeneath the hooks 18 whlchassist in securing the said step or platformin position. The hooks 18 are connected with the side members 15 bymeans of inclined braces 22 which have been shown as being providedwith"quarter-twisted portions 23 intermediate the ends thereof. I 1 Thequarter-twisted portions of the frame bars and the bracesare provided inorder. that the body portions of the side members and braces, as well asthe arms 17, may be dis posedin theproper planes.

The step or platform 20 servesin a meas ureto connect and to space apartthe lower ends of the side members 15. Said side members are alsoconnected together and spaced apart by means of upwardly and forwardly.extending inclined convergent arms 24, each of said arms having one'endsecured to one; of the side members 15 intermediate the ends thereof.The other ends of the arms 24 are bolted or otherwise connectedtogether, and saidarms serve to support a pulley 25 over which aflexible hoisting element, such as a chain 26, is guided. The arms 24are reinforced by means of brace arms 27, each having -oneend secured toone of the side'members 15' near the upper end thereof, and each beingbolted upon or at 28. The arms 27 are provided with terminalJhooks. 29,said ,arms being slightly 'SPacedapart at their forward ends; A.

chain 30 is connected with one of the arms, at 31.

Slidably supported in the keepers. 19 at the upper ends of the framebars 15 are shanks 32, each having at its rearward'end a downwardlyextending hook 33 which, by proper adjustment of the shank, may bevariously spaced from the rearward edge of the frame bar with which itis connected. Each shank 32 has a plurality of apertures 34., for thepassage of a fastening member, such as a bolt 35, whereby it may beadjustably mounted in its keeper. The shanks 32 carrying the hookmembers 33 are intended to be supported on the top edge 36 of the silo,a portion of which has been shown at S, silo walls being of greatlyvarying thickness, varying from two inches, when the wall is constructedof wood, to eight inches or more when the wall is constructed of brick,concrete or the like, thus making it necessary that the hook carryingshanks have a considerable range of adjustment in order that the devicemay be used in connection with silos of many different constructions. Itis, of course, to be understood that the hookcarrying shanks may beengaged not only with the top edge of the silo wall, but also with thesill of any opening or doorway in the silo. V From the foregoingdescription, taken in connection with the drawings hereto annexed, theoperation and advantages of this inventionwill be readily understood bythose skilled. in the art to which it ap'pertains. The operator standingon the step or platform 20 may conveniently manipulate the hoistingelement 26 whereby a blower pipe, indicated at B, may be hoisted intoposition. hen the blower pipe has attained the de: sired elevation, itis'turn'ed so as to present the spout thereof C in the desireddirection, after which the blower pipe is madet'o abut on the hookedextremities of the arms 27 where it is made fast by means of the chain30, some of the links of said chain being.

placed in engagement with the hooks 29, thereby sustaining the blowerpipe securely in position. for operation. After the silo has beenfilled, the pipe may be lowered and the crane detached and stored awayfor future use.

Having thus described the invention, what is claimed as new, is v 1. Inadevice of the class described, a frame comprising side members havingforwardly extending arms at their lower ends, a step supported on saidmembers, supporting means at the upper ends of the side members wherebythe frame may be suspended in position for operation, forwardlyconverging arms supported by the side members, and hoisting meanscarried by said arms.

2. In a device of the class described, a frame comprising members havingfor wardly extending arms at their lower ends, said arms having terminalhooks, inclined braces connecting the hooks with the side members, astep secured on the arms with its forward edge beneaththe hooks, saidstep serving to connect and to'space apart the lower ends of thesidemembers, forwardly convergent arms connected with the side members,means whereby said arms are secured together at their front ends, ahoisting pulley supported by said arms, and means secured at the upperends of the side members whereby the frame may be suspended in positionfor-operation.

3. In a device of the class described, a frame comprising side membershaving for wardly extending arms, a step secured on said arms, forwardlyconvergent arms con nected with the side members, a pulley supported bysaid arms, brace arms connecting the first mentioned arms with the sidemembers, said brace arms'being provided with terminal hooks at theirfree ends, a chain connected withone of the arms, keepers at the upperextremities of the side members, shanks secured slidably and adjustablyin the keepers, and hook members at the rearward ends of the shanks.

4, In a device of the class described, a frame comprising suitablyspaced and connected side members, a stepat the lower ends of the sidemembers, andhoisting mechanism supported by the frame, brace armsreinforcing the brace mechanism and having terminal hooks and achainconnected with one of said brace arms, and means at the upper ends ofthe side members of the frame, whereby said frame may be suspendedinposition for operation.

In testimony whereof I aflix my signature.
